nginx server_name wildcard or catch-all

Question

I have an instance of nginx running which serves several websites. The first is a status message on the server\'s IP address. The second is an admin console on admin.d

Answer 1

If you also want to catch requests with empty Host header (which is allowed in HTTP/1.0) you can use both regex and empty server_name:

server {
    listen      80;
    server_name ~. "";
}
